[view·edit·purge]Ramuh could be based on Lahmu, who is often portrayed as a bearded man with a red sash and four to six curls on his head. Ramuh could also be loosely based on an epic Hindu poem, written by Valmiki, called Ramayana. Its protagonist is Raama (also spelled Rama), said to have been the incarnation of the Hindu god, Vishnu. The name Ramuh could be an amalgam of Raama and Vishnu.

In the Final Fantasy series, Ramuh is an old, bearded sage with a staff who casts thunder magic. He could be based on the king Ra-mu of a supposedly sunken continent, Mu. The element of lightning could come from the Hebrew word רעם (rá'am), meaning thunder, or thunderclap. His previous name, Indra, is the name of the king of the Devas in Hindu mythology, the god of rain, lightning, and storms.
